Need some help
I am a teacher and have a part that I have tried over and over and get very close but cannot get the exact weight. I was wondering if someone would be willing to take a look at the part and then let me see it. This way I can try to understand where I am making the mistake so I can help my students.
Hi, i got the answer, all dimension in this drawing is correct, and i do exactly as drawing. BUT, you have been misread some information, that is "R1 TYP" only stated on two typical area, this not correct. Yes i did try on those two area only, the result is same as you, but after i realized on isometric view, i saw all edges in rounded fillet, come to this conclusion, i make it all R1 on all finished radius, then only i got the answer. (Please see my comment on existing drawing). R1 must apply to all sharp edges as a finishing radius.

Answer C 82.5 (82.49)
There is a dimension missing and a confusing Fillet (TYP)
The pads for the c'sinks. The angle for the outside of the pad is not given; the rad on the top of the pad is not given, the drawing states R1 TYP and R2TYP.
I did 45degree and R1 82.51 and 45degree R2 - 82.49
An other issue? detail B shows the outer rad as full but dimensions state 2.5 thick and 1mm rad each size.
